Mistakes to avoid
Hazard study: identification of external interests to be protected

If your research has shown that you are not concerned by a type of target to be identified (for example, there are no ERP in the vicinity of your installations), this information must be included in your file. If you fail to mention this, anyone reading your file might think that you didn't carry out the research. So, in front of the "ERP" section of your file, note: "None", "Not concerned" or "None" to prove that you have indeed carried out the search.
